4 to 6, the user attaches the DF tag 300 in which the identification information of the tag is recorded to the object 200 to which the tag 200 is to be registered [S110].

The identification information of the DF tag 300 may include an identification number of the DF tag 300 and information related to the object to which the DF tag 300 is attached.

In addition, in the DF tag 300, information indicating the intensity of a signal transmitted from the DF tag 300 and GPS position information of an object to which the DF tag 300 is attached may be further recorded.

At this time, the user may record the identification information in the DF tag 300 by using the DF recording unit 184 or connect the DF tag 300 to an external PC, or may record and store information desired by the user.

The control unit 180 of the portable terminal 100 determines whether the DF tag 300 is attached to the object 200 to which the DF tag 300 is attached according to the user's request, The camera 121 is driven for photographing the camera 200 (S120).

The control unit 180 displays a preview image including the object 200 input through the camera 121 on the display unit 151. When the user inputs an image capture command of the preview image, The DF tag 300 acquires the identification information of the DF tag 300 to be mapped to the photographed object image 400 [S130] (FIG. 5A) S140].

At this time, when the object image 400 is photographed, the control unit 180 drives the DF reader unit 182, receives the identification information from the DF tag 300 through the DF reader unit 182, can do.

When the object image 400 is photographed, the control unit 180 provides the user with an information input window to be used as identification information of the DF tag 300 on the screen of the display unit 151. Thereafter, when the user inputs information to be used as identification information of the DF tag 300 through the information input window, the controller 180 sets the information input by the user as the identification information of the DF tag 300 And transmits the set identification information to the DF tag 300 through the DF reader 182. Then, the DF tag 300 determines the information received from the portable terminal 100 as its own identification information.

As described above, when the identification information of the DF tag 300 is acquired, the controller 180 maps the photographed object image 400 and the obtained identification information of the DF tag 300 to the memory 160 (S150) (Fig. 5 (b)).

5B shows that the identification information of the DF tag 300 attached to the "puppy" 200 is mapped and stored with the image 400 of the "puppy" 200 photographed.

6 (b), when the image 400 of the object 200 to which the DF tag 300 is attached and the identification information of the DF tag 300 are mapped and stored in the memory 160, And so on.

6, the controller 180 displays the gallery menu 510, which stores the photo files provided in the memory 160, in the form of a general picture (not shown) for storing the photo files that are not mapped with the identification information of the DF tag 300 The menu 511 and the favorite photo menu 512 for storing the photo files mapped with the identification information of the DF tag 300. The identification information of the DF tag 300 And the mapped object image 400 may be stored in the favorites photo menu 512.

In this case, the name of the gallery menu 510 generally means a menu for storing photographs in the portable terminal 100, and may be used as a name of a photo storage box, an image viewer, and the like.

As described above, since the photographs in which the identification information of the DF tag is mapped are stored separately, the user can quickly search for and use the photographs containing the object he or she wants to find.

In addition, if there are two or more object images to which the corresponding DF tag identification information is mapped in the favorite photo menu 512, the control unit 180 may classify the object images according to the category of the object and the identification information of the DF tag .

4 and 6, the process of mapping and storing the image including the object to be searched and the identification information of the DF tag attached to the object has been described in detail.

Hereinafter, a process of finding the position of the object to which the DF tag is attached will be described in detail with reference to FIGS. 7 and 8. FIG.

FIG. 7 is a flowchart illustrating a process of searching for the location of an object to which a DF tag is attached according to the present invention.
